Aldoro Resources Ltd (ASX:ARN)'s passive seismic surveys have yielded promising geological insights, particularly in the mapping of pegmatite feeder systems at the Wyemandoo Project in Western Australia.
Surveys were conducted by Fleet Space Technologies, a leader in satellite-enabled passive seismic surveys, delivering 3D geological interpreted models.
The objectives of the surveys were to locate pegmatites with reasonable thickness and identify the main feeders to the dykes, sills and their controlling structures.
During the survey, Aldoro identified a wide deep feature as a possible source of numerous outcropping pegmatites towards the southwest region.
An additional 85 rock chip samples were collected along pegmatite dykes, with mineralised batches to be sent for wet chemistry analysis.
Location of the ANT survey areas Northeast (NE) and Southwest (SW) relative to the anomalous Li2O and Rb rock chip samples.
Survey summary
The surveys covered two specific regions Dome 1 and Dome 2, with previously drilled pegmatites and mapped samples that host lithium and rubidium mineralisation.
Each completed survey spans about 2.4 square kilometres with 64 geodes, initially at 250-metre spacing then focused in along the main zone at 125-metre spacing covering 0.78 square kilometres.
The 250-metre spacing allowed a depth constraint to 500 metres, while the 125-metre spacing provided a shallower 340-metre depth penetration and allowed a higher resolution towards the near surface.
Forward plan
The planned forward work program involves ground follow-up investigations of the 'Zone of Interest' demonstrated via passive seismic survey and potential drilling to determine larger pegmatite feeders.
An additional 85 rock chip samples were collected targeting dykes that were not previously explored.
Samples are currently being screened, with mineralised batches to be sent for wet chemistry.
